Franken admitted on Thursday to posing for a photo while placing his hands on a female performer’s breasts when the two were returning from a 2006 USO tour in the Middle East. The performer, radio host Leeann Tweeden, alleged not only that Franken took the photo while she slept, but that he gave her an unwanted kiss during a rehearsal for one of their joint performances.

In a response released on Thursday, Franken said he had a different memory of that rehearsal but shouldn’t have taken the photo.

“As to the photo, it was clearly intended to be funny but wasn’t. I shouldn’t have done it,” Franken said.
